Hardware: Reset: UND
Description:
The feature is only available for STA310 cut 2.0. This
register is used to enable the autodetection on the S/
PDIF. When high, the autodetection is present. When
low, autodetection is disable.
The STA310 cut 2.0 is able to detect the following au-
dio format changes on the S?PDIF input.
The host must respond to the RST and LCK interrupt
in order for the STA310 to take into account the
change of the audio format.
AUTODETECT_SENS
S/PDIF Autodetection Sensitivity
Address: 0xE1
Type: R/W
Software Reset: 0
Hardware: Reset: UND
Description:
The feature is only available for STA310 cut 2.0. This
register is used to configure the autodetection sensi-
tivity. The lower is SENS, the faster is the autodetec-
tion. Typical value is 0.
